I LOVE Calvin & Hobbes -- I have all of the cartoon books -- I also like it when we see things from the perspective of one of the parents, in which case Hobbes is seen as a stuffed toy, as opposed to the live creature perceived by Calvin.

I knwo it sounds weird, but Calvin sometimes reminds me of me (when I was younger, of course :-)

of Calvin & Hobbes fame -- he replicates himself so he can play while his other selves do his homework. IIRC, there were two sequences, one just involving replication and the other involving Calvins from different times -- and predictably, in both cases the Calvins end up fighting....
